Smartphone applications

Upload to Commons with Android

A free Android app is available for uploading images directly to Commons. (Android 2.3+ operating system required). The tool can be found on Google Play. You may adapt it for your own purposes using the GNU-GPL-licensed source code from GitHub.

Upload to Commons with iOS

An iOS app is also available on the AppStore. The source code is on GitHub under the Apache License.

Upload Wizard - If you are an administrator or image reviewer, you can import images and photosets from Flickr via the Upload Wizard.

Commons Helper

This page will generate code that you can copy and paste when moving an image from a Wikipedia to Commons. Note that you still need to verify the source and only transfer images that have reasonable licenses. You also still need to give the image a category, although the assistant is hooked up to CommonSense, so it can suggest them at the same time. Developed by User:Magnus Manske.

Upload by URL

User's with the upload_by_url right (Image reviewers, Admins, GWToolset users), can directly transfer images from whitelisted websites via the API or via Special:Upload. With the Upload Wizard it is possible to upload files from Flickr.

URL2commons

The URL2commons tool allows all users to directly transfer images from websites to commons.

Internet Archive

IA-upload is available for everyone (uses OAuth). You can select any Internet Archive free book, the description is prefilled and you are given a chance to edit it before upload.

If the desired book is not yet on Internet Archive, you can use BUB (Book Uploader Bot) to request its addition from another source. The job is entirely automatical, accepts requests for multiple books at once and can notify by email when the book is ready, with a link to ia-upload to complete the transfer.

Internet Archive also provides conversion of video from any format to ogv. You are advised to upload the video at the highest quality you have, up to about 400 GB per item.
